When inserting XML DOM Elements inside existing XML DOM Elements that I loaded from an XML file using the following code, none of my new elements were formatted correctly, they just showed up on one line:

<?php $dom = DOMDocument::load('file.xml'); $dom->formatOutput = true;//$dom->add some new elements with child nodes somewhere inside the loaded XML using insertBefore();$dom->saveXML();//output: everything looks normal but the new nodes are all on one line.?>

I found I could pass LIBXML_NOBLANKS to the load method and it would reformat the whole document, including my added stuff:<?php $dom = DOMDocument::load('file.xml', LIBXML_NOBLANKS); $dom->formatOutput = true;//$dom->add some new elements with child nodes somewhere inside the loaded XML using insertBefore();$dom->saveXML();//output: everything looks newly formatted, including new nodes?>
